Verse 4. - That which I have built (comp, Jeremiah 1:10 and parallel passages). Even this whole land; rather, and that is the whole earth.

45:1-5 An encouragement sent to Baruch. - Baruch was employed in writing Jeremiah's prophecies, and reading them, see ch. Jer 36, and was threatened for it by the king. Young beginners in religion are apt to be discouraged with little difficulties, which they commonly meet with at first in the service of God. These complaints and fears came from his corruptions. Baruch had raised his expectations too high in this world, and that made the distress and trouble he was in harder to be borne. The frowns of the world would not disquiet us, if we did not foolishly flatter ourselves with the hopes of its smiles, and court and covet them. What a folly is it then to seek great things for ourselves here, where every thing is little, and nothing certain! The Lord knows the real cause of our fretfulness and despondency better than we do, and we should beg of him to examine our hearts, and to repress every wrong desire in us.Thus shalt thou say unto him,.... This is spoken to Jeremiah, and is an order from the Lord to him, what he should say in his name to Baruch:

the Lord saith thus, behold, that which I have built will I break down, and that which I have planted I will pluck up; the Jewish nation, both as to church and state; which the Lord had built up as a spacious and beautiful house to dwell in, and had planted as a vineyard, and set it with pleasant plants; but now would demolish this building, and destroy this plantation:

even this whole land; not a few cities only, or only Jerusalem the metropolis, but the whole land of Judea; no part of it but what should be left desolate. So the Targum,

"even the whole land of Israel, which is mine.''
